6.5. Hardware Design Example

Follow these steps to test Ethernet-based design examples with enabled auto-negotiation and link training in hardware:
  1. Generate design example as described in Generating the Design.
  2. Modify the .qsf settings:
    • Set device to match the appropriate ordering part number (OPN) for your design.
    • Update the pinout to match the board and the design function.
    • Assign the appropriate VID settings in your .qsf file to match your board.
  3. Generate the .sof file.
  4. Update board clock settings. The default value for the PHY reference clock is 156.25 MHz. The default value for the reconfiguration clock is 100 MHz.
  5. Insert appropriate electrical loopback plug into the Ethernet port.
  6. Program the design.
  7. Open Tools > System Debugging Tools > System Console.
  8. Navigate to the hardware directory <design_example>/hardware_test_design/hwtest directory.
  9. Run the following command in the Tcl shell:
    source main_<Ethernet_rate>.tcl
set_jtag<number_of appropriate_JTAG_master>
  10. Perform these steps if DAC connection is available for UX or patch cable/board to board for BK variants.
    1. Type command to read the seq cfg register:
      reg_read 0x101002C0     [Instance 0]
reg_read  0x102002C0     [Instance 1]
    2. Type command to set the ignore nonce value to 1
      Note:
      • For Ethernet modes (50GE-1, 100GE-2, and 200GE-4) with FEC mode (Ethernet Technology Consortium RS(272, 258)), write to 
        reg_write 0x10100300 0x737d0381   [Instance 0]
reg_write 0x10200300 0x737d0381    [Instance 1]
      • For Ethernet modes (25GE-1, 50GE-2, and 400GE-8) with any FEC mode, write to 
        reg_write 0x10100300 0x737d0381   [Instance 0]
reg_write 0x10200300 0x737d0381	[Instance 1]
      • For other Ethernet modes: 
        reg_write 0x10100300 0x737d0281   [Instance 0]
reg_write 0x10200300 0x737d0281	[Instance 1]
    3. Type command to restart the AN sequencer:
      reg_write 0x101002c0 0x00002003     [Instance 0]
reg_write 0x102002c0 0x00002003	 [Instance 1]
    4. Type command to read the debug status:
      reg_read 0x101003c0            [Instance 0]
reg_read 0x102003c0		    [Instance 1]
      The link is up if the command returns value 1f0.
  11. Sending Frames between two ETH instances[Instance zero has base address 0x0 and instance 1 has base address 0x01000000].
    stop_pkt_gen 0x0
stop_pkt_gen 0x01000000
sleep 2
chkphy_status 0x0
chkphy_status 0x01000000

clear_all_stats 0x0
clear_all_stats 0x01000000

init_packet_rom "<variant_type>" 0x0   [e.g. init_packet_rom "50G" 0x0]
init_packet_rom "<variant_type>"  0x01000000
  12. Type these commands to show TX and RX packets on both instances, and they should match.
    chkmac_stats 0x0
chkmac_stats 0x01000000
The following sample output illustrates a successful hardware test:
